Trichomes are microscopic mushroom-shaped resin glands found on cannabis flowers, sugar leaves, and stems. They're the factories where the plant produces cannabinoids (THCa, CBD, CBG, etc.), terpenes, and flavonoids. Under a macro lens, trichomes look like glass mushrooms — a slender stalk topped by a spherical head. There are three types: bulbous (smallest), capitate-sessile (medium), and capitate-stalked (largest, most abundant on mature flower). Trichome maturity is a harvest-timing signal. Growers use loupes or digital microscopes to inspect trichome color: clear trichomes = underripe, milky/cloudy = peak THC, amber = aged, converting to CBN. Most growers harvest when 70–90% of trichomes are milky with a small percentage amber. Hash production works by separating trichome heads from the plant material through ice-water agitation and micron-screen filtration. The trichome heads, once separated and dried, are essentially pure resin — which is what gets pressed into rosin.
